Ecology And Management Of Rodents In No-Till Agriculture In Washington, Usa, Gary W. Witmer, Rodney Sayler, David Huggins, Jason Capelli
Ecology And Management Of Rodents In No-Till Agriculture In Washington, Usa, Gary W. Witmer, Rodney Sayler, David Huggins, Jason Capelli
USDA Wildlife Services: Staff Publications
No-till farming is an important approach to sustainable agriculture because it can conserve soil and water resources. Unfortunately, rodent populations can thrive under no-till conditions because burrow systems are not disrupted by annual plowing and plant residues build-up on the surface, providing cover and insulation. This can result in substantial crop damage. We assessed rodent populations, habitat use, food habits, and crop damage in a no-till cropping system in Washington, USA. We also conducted preliminary trials of methods to reduce rodent populations and crop damage. In the fall, many more rodents were captured in fields with unharvested crops than in …

Management programs aimed at reducing wildlife damage to row crops rely on information concerning the spatial nature of wildlife damage at local and landscape scales. In this study we explored spatial patterns of wildlife damage within individual corn and soybean fields by describing relationships between specific locations where wildlife damage was recorded and distances from such locations to various habitat types that presumably influenced animal abundance and movements in our study area. Using stratified random sampling, we conducted depredation surveys of 100 corn fields and 60 soybean fields from May through October both in 2003 and 2004 and recorded the …
Crop Diversification Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt
Crop Diversification Leads To Diverse Bird Problems In Hawaiian Agriculture, Marni E. Koopman, William C. Pitt
USDA Wildlife Services: Staff Publications
Over the last 20 years, Hawaii’s agriculture has shifted from a focus on sugar cane (Saccharum officinarum) and pineapples (Ananas comosus) produced on large farms to a diverse array of products produced on a multitude of smaller farms. This dramatic shift in production, in addition to the introduction of many new avian species, has resulted in a concomitant change in the problems faced by agriculture. We surveyed farmers to determine the extent of bird damage to crops, the species responsible, the crops most vulnerable, and control methods employed. Bird problems varied by island, but cardinals ( …
A Hierarchical Analysis Of Habitat Selection By Raccoons In Northern Indiana, James C. Beasley, Travis L. Devault, Monica I. Retamosa, Olin E. Rhodes Jr.
A Hierarchical Analysis Of Habitat Selection By Raccoons In Northern Indiana, James C. Beasley, Travis L. Devault, Monica I. Retamosa, Olin E. Rhodes Jr.

Although numerous studies have examined habitat use by raccoons (Procyon lotor), information regarding seasonal habitat selection related to resource availability in agricultural landscapes is lacking for this species. Additionally, few studies using radiotelemetry have investigated habitat selection at multiple spatial scales or core-use areas by raccoons. We examined seasonal habitat selection of 55 (31 M, 24 F) adult raccoons at 3 hierarchical orders defined by the movement behavior of this species (second-order home range, second-order core-use area, and third-order home range) in northern Indiana, USA, from May 2003 to June 2005. Using compositional analysis, we assessed whether habitat …

Adaptation And Mitigation Strategies In Agriculture: An Analysis Of Potential Synergies, Cynthia Rosenzweig, Francesco Nicola Tubiello
United States National Aeronautics and Space Administration: Publications
As climate changes due to rising concentrations of greenhouse gases in the atmosphere, agriculture will be one of the key human activities affected. Projections show that while overall global food production in the coming decades may keep pace with the food requirements of a growing world population, climate change might worsen existing regional disparities because it will reduce crop yields mostly in lands located at lower latitudes where many developing countries are situated. Strategies to enhance local adaptation capacity are therefore needed to minimize climatic impacts and to maintain regional stability of food production. At the same time, agriculture as …

All U.S. Government Documents (Utah Regional Depository)
In today’s global marketplace, the volume of international trade brings increased potential for the introduction of foreign pests, diseases, and noxious weeds that could threaten the safety of American agriculture. The results of such introductions can have a devastating effect on the U.S. food supply, damage our natural resources, and cost hundreds of millions of dollars in eradication and control measures that ultimately result in higher priced agricultural products for the consumer.

Generalized Geologic Map For Land-Use Planning: Hart County, Kentucky, Daniel I. Carey, Joshua J. Johnson
Map and Chart--KGS
This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.
